' To all whom it may concern:

till

Be it known that I, DURELL Press, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Method of and Apparatus for Making Composite Threads, of which the following is a specification.

This invention relates to a method of and apparatus for making a composite thread, especially a thread havin a plurality of metallic wires twistedran combined with one or more threads of fibrous material. Heretofore in the manufacture of threads of this character trouble has been experienced from the un ual delivery of the wires as the same are pu led forward by the drawing rolls especially when the bobbins or spools of wire are unequally unwound which has impaired thequality of the resulting thread and has weakened the same as if one wire is longer than the other, or kinked, the strain will have to come on the shorter or straight wire which leads to difiiculty and breakage in the weaving.

My improved method overcomes this difiiculty by the employment of a means forlay- .ing the two wires exactly parallel and then looping them'under the sametension to secure equality of length or remove the kinks.

Apparatus by which my invention may be practiced is illustrated in the accompanying drawing, in which Fig. 1 is a diagrammatm vertical sectional view of a ortion of a flier twisting machine arranged invention;

Fig. 2 is a front view, and Fig. 3 a side elevation respectively on an enlarged scale showing the mechanism which I employ for the above stated apparatus;

Fig. 4 is a fmnt'elevation and Fig.5 a-

side elevation on the same enlarged-scale of the assembled parts; and

Fig. 6 illustrates a modified form of guiding roller.

Referring to the drawin and in detail A represents one or more bo' bins from which one or more strands B are led to an assembing thread guide Q. As many strands may be employe as desired, three being illustrated as employed for making up a completed thread. D designates a plurality of spools or bobbins woundwith wire strands E. The wire strands are led from the spools through a pig-tail. or wire guide. 15, then for the practicing of my around a roller G, then up around the roller H to the assembling thread guide C. It will be noticed that the wire strands are thus led between the roller G and the assembling thread uide C. The strands B and E are drawn i orward from the assembling thread guide by positively driven top or friction rollers l and then the assembled strands are led to a spinnin couple which preferably is of the difierential flier or throstle type or it may be a rin and traveller. It will be noticed that eat; vided with a groove which is curved in crosssection and which is shaped so as to lay the two wire strands E closely together and arallel. The two wire strands bein looped in this position the kinks or inequa 'ties of length are removed as the looping is done under the tension of the drawing or top rollers I. The grooves in the rollers G and H may have curved bottoms as illustrated in Fig. 2 or may have a fiat bottom with reentrant sides as illustrated in Fig. 6. d designates a railing which may be secured in the spinning frame and the wire ide F and t e spindles or pins for the re ers G and ll for each spindlemay be secured in a bracket K attached to said rail .l. By assembling the strands in this manner and by laying the two metallic strands parallel and loop: ing them under tension before they are assembled with the strands B, a composite thread of the character described may be spun or manufactured with practically no kinks or irregularities thereby producing a smooth even y witheach wire strand of equa length.

The details and arrangements herein shown and described may be greatly varied by a skilled mechanic without departing from the scope of the invention as expresse in the claims.

Having thus described my invention what I declare and desire to secure by Letters Patent is 2- 1 1. The method of m r a composite thread which consists in drawings. plurality of wire strands forward throu to equalize and remove kinks t ereirom, applying a fibrpus strand or strands therewith and twisting the strands together to make.

a composite thread.

2. The method of malm'ng a composite thread which consists in drawm a plurality of wire strands forward in. para el position twisted com osite thread loop form roller G and H is prov.

through loop form to equalize and remove or strands therewith,

kinks therefrom, assembling a fibrous strand and twisting the strands together to make a composite thread.

3. The combination of drawing rolls arranged to draw forward a plurality of metallic and fibrous strands and associate them together, a looping device applied. to the metallic strands before the drawing rolls, and a twisting couple for twisting the strands together.

4. The combination of drawing rolls arranged to draw forward a pluralit of metallic and fibrous strands and associate them together, and a looping device applied to the metallic strands before the drawing rolls consisting of rollsand an assemblingthread guide.

5. The combination of drawing rollers arran ed to draw forward a plurality of metalhc and fibrous strands and associate them together, and a looping device applied to the metallic strands before the drawing rollers consisting of rollers having grooves tapered in cross-section and an assembling thread guide.

6. The combination of drawin rolls arranged to draw forward a plurality of metallic and fibrous strands and associate them together, a looping device applied to the metallic strands before the drawing rolls consisting of a wire guide, grooved rollers and an assembling thread guide to which latter the fibrous strands are led, and a twisting couple for twisting the strands together.

7. A spinning frame having drawing rolls, a rail carried by the spinning frame, brackets carried by the rail, each havin grooved rollers, and a wire guide and assembling thread guide to which the fibrous strands are led, and a twisting couple for twisting the strands to ether.

In testimony whereo I have hereunto affixed my signature.
